Made a custom tube pipe to fit the k&n typhoon filter, that thing sucks like a typhoon indeed, but it dropped the boost from 25 psi to 18 psi and it's not stable. Can it be the maf sensor if it's placed a bit more forward? Any thoughts of why this happened are welcomed, thank you in advance, pics below....

Kagem,

Beautiful work you did!

Not to be a naysayer, but you took a highly efficient stock design and dumbed it down with a restrictive design. No CAI will beat the stock air cleaner design, though most don't reduce the flow like your's appears to do.

I would think that your MAF sensor is too close to the filter. Is the air coming in too turbulent for the MAF sensor to get an accurate reading?

For intake I think it needs a re-tune to calibrate the MAF readings.

i didn't re tune for my Dejon intake and so far no problems.
IMHO the MAF is not placed at the correct place..maybe a bit to the front...

the location of the Maf looks similar to the location of Mine
I'm wondering if the diameter of the pipe is too large, ie too much airflow
if that's the case, a re-tune could help, or make a smaller pipe.

very nice welds!!!

Too bad too as you did a beautiful job on it Kagem.

Thank you all for your opinions! I just came back from the dealership while driving there i suddenly had no boost at all, like limp mode but no check light. My mechanic there tested the car by stepping on the gas and the ic tubes where growing normally, but zero boost. He turned off the car, turned it on again and voila there was boost again. We tested it at the road also and the boost was hitting 25 psi like always. He told me to drive the car like i used to do and if there is something not working properly we will know about it with a check light. Maybe i suppose the tune needs a little time until it learns this mode, Vince once told me that i would not need a new tune for an exhaust or even an ic. It sounds excessive to need an updated tune for only an intake while you don't need for an exhaust or an ic. Any suggestions are welcomed....

best guess is that the car just didn't know what to do with the change in incoming air. No surprise that it took a few key cycles to adjust to the change.

Kagem two things to check.
make sure the Maf is placed in the correction direction (?? quite impossible but $hit happens)
and check the MAF for oil and debris. maybe clean it also.

Kagem · « **Reply #10 on:** March 17, 2011, 12:59:40 PM »

Maybe you're right GJ, just scanned for codes and there was the p0101 code about the maf, but no check engine light. I cleared it and i'll check again in a while if this code comes again. Let's hope it doesn't. George i'll do what you said, thanks pal!

Kagem: I agree about no re-tune for IC but I don't agree about downpipe or intake. I would log fuel trims and lamnda after intake is changed, if fuel trims are off means that MAF readings are off and needs a recalibration.

I think the best is to drive it through a few key cycles and see what happens.
Also on the GMPP intake the MAF is pretty close to the filter, however I would wait for the key cycles before doing anything else.
Kelu, does have a point but I would not do any logs until you run through a few key cycles.

Your words are a big relief, thanks LV! That's what my mechanic told me, to drive it for a while and see how it reacts. I talked with Vince and he told me to send him logs, it's better to be safe than sorry. What matters most of all is the mixture, i don't want it too lean in high rpm range because there will be a problem, and that is what i fear with the mode i made now with the air intake. I hope to solve this issue as soon as possible....

The issues with the typhoon intake still occur, yesterday reflashed with the same tune as for the ecu to start over with the new intake and learn form scratch during the key cycles, hoping to get it to work within a few hundred miles. Recorded today using two cams, one inside the car showing the rpm action and one above the engine showing the intake, both while starting the car. Watching the videos you can hear the hiccups coming from the intake and affecting the engine. Opinions and guidance needed, happy Sunday to all kappa owners!

If you still have the stock intake, why don't you put that back on just to see if the problem is the intake, or possibly something else.

Arabas · « **Reply #16 on:** March 20, 2011, 11:40:56 AM »

Kagem, IMHO, take it off and put the stock one back or order an intake that you know will be working correctly.

IMHO the filter is TOO close to the MAF and the flow it is reading is either $hit or turbulenced or something...
take a look at the fotos below, the distence between the original tube of K&N Typhoon and yours are very very different. In yours the MAF is much closer to the filter

K&N

Yours

Hercules (auto shop) is good at making IC and radiators of any kind, BUT IMHO he does not know anything about cars and mods. he is just a good craftmanship and does well what he's told. air flow is much more than this, especially in our weirdow kappa.

BTW, what did Vince tell you about your A/F ratio?

Kagem · « **Reply #17 on:** March 20, 2011, 11:47:43 AM »

This is one of my thoughts. Another thought is to trade intakes with a friend who has dejon and see if it does this to his car too, and after that also trade maf sensors. If my intake is the problem then yes i will put the stock intake back until i get another intake probably aftermarket that shall work for sure without issues.
George i haven't got an answer yet form Vince, still waiting....

elff · « **Reply #18 on:** March 20, 2011, 12:00:05 PM »

I have a better idea
Put his dejon in your car, reset codes, test drive.

Arabas · « **Reply #19 on:** March 20, 2011, 12:02:59 PM »

did you check if maf is facing the right direction?
also checked if maf has dirt/oil on it?

Kagem · « **Reply #20 on:** March 20, 2011, 12:08:34 PM »

Putting his dejon will 99% work, the question is if my intake will work in his car, my intake is the problem. The maf is facing the right direction yes, if it has any dirt/oil on it i suppose not, but i can check. I remember you had cleaned yours right? Do you have these guides? Thanks!

Arabas · « **Reply #21 on:** March 20, 2011, 12:15:33 PM »

clean MAF

You should split your issue into a new thread

Then we can more easily find it in the future for reference.

Kagem · « **Reply #23 on:** March 20, 2011, 02:12:45 PM »

Thanks for the link George!
Nice suggestion Kenny, it's up to the moderators, i'll keep it updated....

LatinVenom · « **Reply #24 on:** March 20, 2011, 04:52:59 PM »

My bet it is going to do the same thing on his car.
Does he also have a Trifecta tune?.
Vince will probably come back with an update to the tables.
My other point is the car is cold. What happens after the car is up to the proper temperature?.
My car with the BIG wheel when is started it and is cold it sounds really weird.
Once it settles and goes below 1K RPM it is just like any other OEM K04.
